GL Inverse Rate Not Calculating Correctly

Hi,

I am finding a cause on what made the calculations of the GL Daily Rates wrong.

Our end-user entered a certain amount in USD to PHP using the rate type of Philippine Corporate Exchange Rate.

From amount: 56.179
To amount: 2.5799793602 (wrong inverse rate)

And another one but USD to JPY:

From amount: 144.93

To amount: 144.9275362319 (wrong inverse rate)

On the week after this, the end-user tried to enter the same from amount again and the inverse rates are now correct.

We have been investigating regarding the cause of this issue in order for us to understand and prevent it in the future.
